To alf ali/tom t may camera:

Be it known that i tizen ot' the Uni f i ying at Dallas, in .Y and Stateof Texas have invented cer. new and useful improvements in Too which thefollowing is a speciiica-tion.

rlhis invention relates to new and useful improvements in rim tools.

The object of the invention is to provide a rim tool for disjointing andjointing th' split rims of automobile wheels tor the pur pose otremoving and replacing the tire casings.

A particular object of the invention is to provide means for spreadingthe split ends ot' the rim apart prior to their radial dis- This isirnportant in order to free the latching means and provide for an easyand quick disjointing or breaking of the rim.

A further object is to provide means tor adjusting the tool to variouswidths in connection with a lateral adjustment ior anplying the tool tothe rim.

An object of the invention is to 'torni ends of the riin engagingfingers so as t remain in the sockets of the rini.

Af `still further object is to provide an arched or yoke shapedconnection between the rim engaging elements7 on each side, which makesfor an easy disjointing ci? the ends 01"' the rim.

A construction designed to carry out tac invention will be hereinafterdescribed to gether with other 'features ot the invention.

rlhe invention will be more readily understood from a reading of thefollowing si ication and by reference to the acconipar f ing drawings,in which an example ci invention is shown, and wherein:

Fig. 1 is a plan view ot a tool constructed in accordance with myinvention and applied to a rim.,

Fig. 2 is an enlarged view oli the widt'ai adjusting sleeve connection,

Fig. 3 is a longitudinal sectional view on the line 3-3 of Fig. 1 andFig. 4 is an enlarged cross-sectional view on the line lf-4 of Fig. 1.

ln the drawings the numeral 1G designates a lever having a screwthreaded portion 10 which forms one side member ot the tool, a similarlever 11 having a threaded pon tion 11, forming the other side. Theinner side of each portion 10 and 11 respectivelg.

Lon the j posite end of the col ith a longitudinal key-way 12. collar 13is slidable in each il Each collar has a key 1itherein, but tree toslide in one ot' key-ways. r@his prevents the levers 'in the collarswhich .are free to slide sail levers. j

Each lever has one end reduced and bent at right angles to Jform afinger 15, the eX- treniity oiQ which is provided with av button i6. Foreach collar 13 is provided an ad justing nut 1T engaging the end nearestthe linger and a stop nut l'engaging the oplar. Thus by screwing thenuts 17 on the portions 10 and 11, in one direction the collars are slid`away from the ingers, the nuts 18 having bee'npreviously backed ofi topermit the sliding of the collars. By reversing the operation thecollars may be slid toward the lingers 15.'

At the center of each collar is formed a boss 20, from the inner side ofwhich a linger 15 extends inwardly and has a button 16 on its end. Thebuttons 16 are substantially iiush with the buttons 16. The bosses 20extend above the collars and have ears 21 at the upper ends receivingthe trunnions 22 of the' angular legs of a yoke or bail 23. Thetrunnions are shouldered so as to limit their outward displacement inthe ears. @n the outer screw-threaded end of each trunnion is mounted anut 24 bearing against the ear.

The legs of the yoke telescope into a sleeve 25 and are provided withgrooves 26 receiving set screws 27, whereby the legs may be fastened inthe sleeve. By adjusting the legs the width between the collars andlevers and the ngers carried thereby may be regulated and thus the. toolis set for the width of the rim with which it is to be used.

The rim with which the tool is to be used is provided with notches orsockets A on its side edges or flanges on each side of its split B. Thebuttons 16 oi the fingers 15 are engaged in sockets in one end of therim and on opposite sides, while the buttons 16 of the fingers 15 areengaged in the sockets in the other endet the rim. The buttons willengage and remain in the sockets more eiliciently than the reduced endsoi' the fingers. otherwise would, and will not be displaced so easilyowing to their increased bearing surfaces.

@ne of the nuts 24 is loosened to spread the ngers so that they may loevengaged in the sockets and by tightening said nut the fingers will beheld in the rim. rEhe sleeve adjustment is used for different widths ofrims. Y V

On each side of the rim the finger 15 will engage the sockets in one endof the rim,

while the fingers 15 will engage the sockets in the other end of therim, the split B lying between the fingers 15 and the fingers 15. Byturning the nuts 17 in a clockwise direc tion the collars 13 are slidaway Vfrom the fingers 15, whereby the fingers 15 carry the en of therim with them. This separates the split ends of the rim suiiciently todisengage any latch connections.

When the ends of the rim have been spread the levers will extend on eachside of the rim. The operator places the soles of his shoes on thelevers and presses down thereon which distorts the rim ends radially andpermits any latch or fastening element to be freed. He next catches holdof the levers and swings the same upwardly and forwardly whereby thefingers 15 become fulcrums and the fingers 15 are swung in an arcconcentric thereto. This carries the end of the rim connected with thefingers 15 inward and circumferentially over the other end of the rim,whereby the ends are overlapped and the rim broken sothat the casing canbe easily removed and replaced. By swinging the levers in the op positedirection the rim is restored toits normal position.

What I claim, is:

1. In a rim tool, a pair of levers having rim engaging elements, a pairof collars slidable on said levers, rim engaging elcments carried by thecollars, ineans for adjustlng the collars to space their rim engagingelements from the lever rim engaging elements, and means for connectingthe collars and the levers together transversely.

2. In a rim tool, a pair of levers having rim engaging elements, a pairof collars slidable 'on said levers, rim engaging elements carried bythe collars, means for adjusting the collars to space their rim engagingelements from the lever rim engaging elements, and a .yoke extendingtransversely between and pivot-ally connected to the collars, saidcollars being laterally adjustable on said yoke.

3. In a rim tool, a pair of levers having rim engaging elements, a pairof collars slidlongitudinally on the levers and carryingk rim engagingelements, nuts threaded on the levers at each end of the collars foradjusting the same, a yoke comprising legs adjustably telescoping into aconnecting sleeve and trunnions pivoted to the, collars, and nutsengaging the trunnions of the yoke for confining the collars thereon.

In testimony whereof` I afiix my signature.

JAMES P. GILES.
